The Catalyst 2960-X switches comes with one fixed power-supply and options for an external redundant power
supply source (RPS2300).
The Catalyst 2960-XR switches support dual redundant power supplies. The Catalyst 2960-XR ships with one
power supply by default. The second power supply can be purchased at the time of ordering the switch or as a
spare. These power supplies have in-built fans to provide cooling.
